20-Bit Bus Switch with Level Shifting

General Description

Features

The Fairchild Switch FSTD16861 provides 20-bits of high-

speed CMOS TTL-compatible bus switching. The low On

Resistance of the switch allows inputs to be connected to

outputs without adding propagation delay or generating

additional ground bounce noise. A diode to V_CChas been

■ 4 switch connection between two ports.

■ Minimal propagation delay through the switch.

■ Low l_CC

■ Zero bounce in flow-through mode.

■ Control inputs compatible with TTL level.

integrated into the circuit to allow for level shifting between

5V inputs and 3.3V outputs.

■ TruTranslation voltage translation from 5.0V inputs to

3.3V outputs

The device is organized as a 10-bit or 20-bit bus switch.

When OE₁is LOW, the switch is ON and Port 1A is con-

■ Power-off high impedance inputs and outputs

■ Supports live insertion/withdrawal (Note 1)

Note 1: To ensure the high-impedance state during power up or power

down, OE should be tied to V

nected to Port 1B. When OE₂is LOW, Port 2A is connected

to Port 2B. When OE_Xis HIGH, a high impedance state

exists between the A and B Ports.

through a pull-up resistor; the minimum

value of the resistor is determined by the current-sourcing capability of the

driver.
